X509_get_pubkey() attempts to decode the public key for certificate
x. If successful it returns the public key as an
EVP_PKEY
pointer with its reference count incremented: this means the returned key must
be freed up after use.
X509_get0_pubkey() is similar except it does
not increment the reference count of the returned
EVP_PKEY so it
must not be freed up after use.
X509_get_X509_PUBKEY() returns an internal pointer to the
X509_PUBKEY structure which encodes the certificate of
x. The
returned value must not be freed up after use.
X509_set_pubkey() attempts to set the public key for certificate
x
to
pkey. The key
pkey should be freed up after use.
X509_REQ_get_pubkey(),
X509_REQ_get0_pubkey(),
X509_REQ_set_pubkey() and
X509_REQ_get_X509_PUBKEY() are similar
but operate on certificate request
req.
The first time a public key is decoded the
EVP_PKEY structure is cached
in the certificate or certificate request itself. Subsequent calls return the
cached structure with its reference count incremented to improve performance.
X509_get_pubkey(),
X509_get0_pubkey(),
X509_get_X509_PUBKEY(),
X509_REQ_get_pubkey() and
X509_REQ_get_X509_PUBKEY() return a public key or
NULL if an
error occurred.
X509_set_pubkey() and
X509_REQ_set_pubkey() return 1 for success
and 0 for failure.
